Raspberry Pi Ua kom muaj zog dua File System User Guide

Raspberry Pi Ltd cov khoom siv tau nquag siv los ua cov ntaub ntawv khaws cia thiab saib xyuas cov cuab yeej, feem ntau nyob rau hauv qhov chaw uas muaj hluav taws xob tam sim ntawd tshwm sim. Raws li nrog rau txhua yam khoom siv hauv computer, lub hwj chim poob tuaj yeem ua rau kev cia khoom tsis zoo. Daim ntawv dawb no muab qee cov kev xaiv los tiv thaiv cov ntaub ntawv kev noj nyiaj txiag raws li cov xwm txheej no thiab lwm yam los ntawm kev xaiv qhov tsim nyog file systems thiab teeb tsa kom ntseeg tau cov ntaub ntawv ncaj ncees. Daim ntawv dawb no xav tias Raspberry Pi tab tom khiav Raspberry Pi (Linux) kev khiav haujlwm (OS), thiab ua tiav nrog cov firmware tshiab thiab cov kernels.

Cov ntaub ntawv kev noj nyiaj txiag yog dab tsi thiab vim li cas nws tshwm sim?
Cov ntaub ntawv kev noj nyiaj txiag yog hais txog kev hloov pauv tsis xav tau hauv cov ntaub ntawv hauv computer uas tshwm sim thaum sau ntawv, nyeem ntawv, khaws cia, xa tawm, lossis ua haujlwm. Hauv daim ntawv no peb tsuas yog xa mus rau kev khaws cia, tsis yog kev sib kis lossis kev ua haujlwm. Kev tsis ncaj ncees tuaj yeem tshwm sim thaum cov txheej txheem sau ntawv cuam tshuam ua ntej nws ua tiav, hauv txoj hauv kev uas tiv thaiv kev sau tsis tiav, rau example yog lub zog poob. Nws yog qhov tsim nyog ntawm lub sijhawm no muab cov lus qhia ceev ceev li cas Linux OS (thiab, los ntawm kev txuas ntxiv, Raspberry Pi OS), sau cov ntaub ntawv rau kev khaws cia. Linux feem ntau siv sau caches los khaws cov ntaub ntawv uas yuav tsum tau sau rau khaws cia. Cov cache no (kho ib ntus) cov ntaub ntawv nyob rau hauv random access memory (RAM) kom txog rau thaum ib tug tej yam predefined txwv tau mus txog, nyob rau hauv uas taw tes tag nrho cov zoo sau rau hauv nruab nrab cia yog ua nyob rau hauv ib tug lw. Cov kev txwv ua ntej no tuaj yeem yog lub sijhawm thiab / lossis qhov loj me. Rau example, cov ntaub ntawv yuav raug cached thiab tsuas yog sau rau khaws cia txhua tsib vib nas this, lossis tsuas yog sau tawm thaum qee cov ntaub ntawv tau sau tseg. Cov tswv yim no yog siv los txhim kho kev ua tau zoo: sau cov ntaub ntawv loj hauv ib qho mus sai dua li sau ntau cov ntaub ntawv me me.

Txawm li cas los xij, yog tias lub zog poob ntawm cov ntaub ntawv khaws cia hauv cache thiab nws raug sau tawm, cov ntaub ntawv ntawd ploj. Lwm yam teeb meem tshwm sim tshwm sim ntxiv rau hauv cov txheej txheem sau ntawv, thaum lub sij hawm sau lub cev ntawm cov ntaub ntawv mus rau qhov nruab nrab cia. Ib zaug ib daim hardware (example, Kev Ruaj Ntseg Digital (SD) daim npav interface) tau hais kom sau cov ntaub ntawv, nws tseem siv sijhawm ntev rau cov ntaub ntawv ntawd kom khaws lub cev. Ntxiv dua thiab, yog tias lub zog tsis ua haujlwm tshwm sim thaum lub sijhawm luv luv, nws muaj peev xwm ua rau cov ntaub ntawv raug sau ua kev puas tsuaj. Thaum kaw lub khoos phis tawj, suav nrog Raspberry Pi, kev coj ua zoo tshaj plaws yog siv qhov kev xaiv kaw. Qhov no yuav xyuas kom meej tias tag nrho cov ntaub ntawv cached raug sau tawm, thiab cov khoom siv tau muaj sijhawm los sau cov ntaub ntawv mus rau qhov nruab nrab cia. SD phaib siv los ntawm feem ntau ntawm Raspberry Pi ntau yam ntawm cov khoom siv zoo li pheej yig nyuaj hloov pauv, tab sis muaj kev cuam tshuam rau kev ua tsis tiav dhau sijhawm, nyob ntawm seb lawv siv li cas. Lub cim xeeb flash siv nyob rau hauv SD phaib muaj qhov txwv sau lub voj voog lub neej, thiab raws li daim npav mus txog qhov txwv lawv tuaj yeem ua tsis tau. Feem ntau SD daim npav siv cov txheej txheem hu ua hnav leveling kom paub tseeb tias lawv nyob ntev li ntev tau, tab sis thaum kawg lawv tuaj yeem ua tsis tiav. Qhov no tuaj yeem yog los ntawm lub hlis mus rau xyoo, nyob ntawm seb cov ntaub ntawv tau sau ntau npaum li cas, lossis (tseem ceeb dua) tshem tawm ntawm daim npav. Lub neej no tuaj yeem sib txawv heev ntawm daim npav. SD card tsis ua hauj lwm feem ntau yog qhia los ntawm random file kev noj nyiaj txiag raws li ib feem ntawm SD card yuav siv tsis tau.

Muaj lwm txoj hauv kev rau cov ntaub ntawv los ua corrupted, suav nrog, tab sis tsis txwv rau, cov khoom nruab nrab tsis zoo, kab laum hauv kev khaws cia-sau software (tsav tsheb), lossis kab laum hauv daim ntawv thov lawv tus kheej. Rau lub hom phiaj ntawm daim ntawv dawb no, txhua tus txheej txheem los ntawm cov ntaub ntawv poob tuaj yeem tshwm sim tau txhais tau tias yog kev noj nyiaj txiag.

Dab tsi tuaj yeem ua rau kev sau ntawv?
Cov ntawv thov feem ntau ua qee yam kev sau ntawv rau kev khaws cia, piv txwvample configuration ntaub ntawv, database tshiab, thiab lwm yam. Ib txhia ntawm no files tej zaum yuav yog ib ntus, piv txwv li tsuas yog siv thaum qhov kev pab cuam tab tom khiav, thiab tsis tas yuav tsum tau khaws cia dhau lub voj voog hluav taws xob; txawm li cas los xij, lawv tseem ua rau sau ntawv mus rau qhov nruab nrab cia. Txawm hais tias koj daim ntawv thov tsis tau sau cov ntaub ntawv tiag tiag, hauv keeb kwm yav dhau Linux yuav tas li sau ntawv mus rau qhov chaw cia, feem ntau sau cov ntaub ntawv nkag.

Kev daws teeb meem kho vajtse

Txawm hais tias tsis yog tag nrho hauv kev xa tawm ntawm daim ntawv dawb no, nws tsim nyog hais tias kev tiv thaiv kev poob qis ntawm lub zog poob qis yog ib qho kev siv ntau thiab nkag siab zoo tiv thaiv cov ntaub ntawv poob. Cov khoom siv xws li cov khoom siv hluav taws xob tsis cuam tshuam (UPSs) kom ntseeg tau tias cov khoom siv hluav taws xob tseem ruaj khov thiab, yog tias lub zog poob rau UPS, thaum lub roj teeb lub zog nws tuaj yeem qhia rau lub khoos phis tawj tias lub zog poob yuav tshwm sim kom kaw tuaj yeem ua tau zoo ua ntej lub zog thaub qab khiav tawm. Vim tias SD daim npav muaj lub neej tsawg, nws yuav muaj txiaj ntsig kom muaj kev hloov pauv uas ua kom cov npav SD hloov ua ntej lawv muaj sijhawm mus txog qhov kawg ntawm lub neej.

Muaj ntau txoj hauv kev uas Raspberry Pi ntaus ntawv tuaj yeem ua kom tawv nqaij tiv thaiv kev noj nyiaj txiag. Cov no sib txawv hauv lawv lub peev xwm los tiv thaiv kev noj nyiaj txiag, nrog rau txhua qhov kev ua kom txo tau qhov tshwm sim.

Txo cov ntawv sau
Tsuas yog txo tus nqi sau ntawv uas koj cov ntawv thov thiab Linux OS tuaj yeem muaj txiaj ntsig zoo. Yog tias koj ua ntau qhov kev txiav txim siab, ces qhov muaj feem ntawm kev sau ntawv tshwm sim thaum muaj kev noj nyiaj txiag ntau ntxiv. Txo kev nkag rau hauv koj daim ntawv thov yog nqes mus rau cov neeg siv kawg, tab sis kev nkag rau hauv Linux kuj tuaj yeem txo. Qhov no yog qhov tshwj xeeb tshaj yog tias koj siv flash-based cia (xws li eMMC, SD phaib) vim lawv txwv kev sau lub neej.

Hloov cov sij hawm cog lus
Lub sijhawm cog lus rau a file system yog lub sij hawm uas nws caches cov ntaub ntawv ua ntej nws luam tag nrho rau cia. Kev nce lub sij hawm no txhim kho kev ua tau zoo los ntawm kev sib sau ntau ntawm kev sau, tab sis tuaj yeem ua rau cov ntaub ntawv poob yog tias muaj teeb meem kev noj nyiaj txiag ua ntej cov ntaub ntawv sau. Txo lub sijhawm ua haujlwm yuav txhais tau tias tsawg dua ntawm kev ua tsis ncaj ncees ua rau cov ntaub ntawv poob, txawm tias nws tsis tiv thaiv nws tag nrho.
Txhawm rau hloov lub sijhawm cog lus rau lub ntsiab EXT4 file system ntawm Raspberry Pi OS, koj yuav tsum hloov kho \etc\fstab file uas txhais li cas file systems yog mounted rau startup.
$ sudo nano /etc/fstab

Ntxiv cov hauv qab no rau EXT4 nkag rau hauv paus file qhov system:

cog =

Yog li, fstab yuav zoo li qhov no, qhov twg lub sijhawm cog lus tau teem rau peb vib nas this. Lub sij hawm cog lus yuav ua rau tsib vib nas this yog tias tsis tau teem tseg.

Ib ntus file tshuab

Yog tias daim ntawv thov xav tau ib ntus file cia, piv txwv li cov ntaub ntawv tsuas yog siv thaum daim ntawv thov tab tom khiav thiab tsis tas yuav tsum tau txais kev cawmdim dhau qhov kev kaw, ces qhov kev xaiv zoo los tiv thaiv lub cev sau rau kev cia yog siv ib ntus. file system, twm. Vim cov no file systems yog RAM raws li (qhov tseeb, hauv lub cim xeeb virtual), txhua cov ntaub ntawv sau rau tmpfs yeej tsis tau sau rau hauv lub cev cia, thiab yog li tsis cuam tshuam rau lub neej flash, thiab tsis tuaj yeem ua puas tsuaj los ntawm kev noj nyiaj txiag.
Tsim ib lossis ntau qhov chaw tmpfs yuav tsum tau kho qhov /etc/fstab file, uas tswj tag nrho cov file Cov kab ke hauv qab Raspberry Pi OS. Cov nram qab no example hloov qhov chaw cia-raws li /tmp thiab /var/log nrog ib ntus file qhov chaw nyob. Ob example, uas hloov tus txheej txheem logging nplaub tshev, txwv tag nrho qhov loj ntawm lub file system mus rau 16 MB.

tmpfs / tmp tmpfs defaults, noatime 0 0
tmpfs /var/log tmpfs defaults,noatime, size=16m 0 0

Kuj tseem muaj tsab ntawv thib peb uas pab teeb tsa kev nkag mus rau RAM, uas tuaj yeem pom ntawm GitHub. Qhov no muaj qhov ntxiv feature ntawm dumping RAM-raws li lub cav rau disk ntawm lub sijhawm ua ntej.

Nyeem nkaus xwb hauv paus file tshuab

Lub hauv paus file system (rootfs) yog qhov file system ntawm lub disk muab faib uas lub hauv paus directory nyob, thiab nws yog file system uas tag nrho lwm yam file systems yog mounted thaum lub system yog booted. Ntawm Raspberry Pi nws yog /, thiab los ntawm lub neej ntawd nws nyob ntawm SD daim npav raws li kev nyeem / sau tag nrho EXT4 muab faib. Kuj tseem muaj lub khau raj khau raj, uas yog mounted li / khau raj thiab yog nyeem / sau FAT muab faib. Ua cov rootfs nyeem nkaus xwb txwv tsis pub muaj kev sau ntawv nkag mus rau nws, ua rau nws muaj zog ntau dua rau cov xwm txheej kev noj nyiaj txiag. Txawm li cas los xij, tshwj tsis yog lwm yam kev nqis tes ua, qhov no txhais tau tias tsis muaj dab tsi tuaj yeem sau rau hauv file system txhua, yog li txuag cov ntaub ntawv ntawm txhua yam los ntawm koj daim ntawv thov mus rau rootfs yog neeg xiam. Yog tias koj xav khaws cov ntaub ntawv los ntawm koj daim ntawv thov tab sis xav tau cov ntawv nyeem nkaus xwb, cov txheej txheem ib txwm yog ntxiv USB nco lo lossis zoo sib xws uas tsuas yog khaws cia cov neeg siv cov ntaub ntawv.

Nco tseg
Yog tias koj siv qhov sib pauv file thaum siv cov ntawv nyeem nkaus xwb file system, koj yuav tsum tau txav lub swap file mus rau ib tug nyeem/sau muab faib.

Overlay file qhov system

Ib qho overlay file system (overlayfs) ua ke ob file systems, ib sab file system thiab qis dua file qhov system. Thaum lub npe muaj nyob rau hauv ob qho tib si file systems, cov khoom nyob rau sab sauv file system yog pom thaum cov khoom nyob rau hauv qis file system yog zais los yog, nyob rau hauv cov ntaub ntawv ntawm cov directory, merged nrog rau lub sab sauv khoom. Raspberry Pi muab kev xaiv hauv raspi-config los pab kom muaj kev sib tshooj. Qhov no ua rau cov rootfs (qis dua) nyeem nkaus xwb, thiab tsim lub RAM raws li sab saud file qhov system. Qhov no muab cov txiaj ntsig zoo sib xws rau kev nyeem nkaus xwb file system, nrog rau tag nrho cov neeg siv kev hloov pauv tau ploj ntawm reboot. Koj tuaj yeem ua kom muaj kev cuam tshuam los ntawm kev siv cov kab hais kom ua raspi-config lossis siv lub desktop Raspberry Pi Configuration daim ntawv thov ntawm cov ntawv qhia nyiam.

Tseem muaj lwm qhov kev siv ntawm overlayfs uas tuaj yeem synchronize xav tau kev hloov pauv ntawm sab sauv mus rau sab qis file system ntawm lub sijhawm teem tseg. Rau example, koj tuaj yeem luam cov ntsiab lus ntawm tus neeg siv lub tsev nplaub tshev los ntawm sab saud mus rau qis dua txhua kaum ob teev. Qhov no txwv cov txheej txheem sau ntawv mus rau qhov chaw luv luv ntawm lub sijhawm, txhais tau tias kev noj nyiaj txiag tsawg dua, tab sis txhais tau tias yog lub zog ploj ua ntej synchronisation, cov ntaub ntawv tsim tawm txij li qhov kawg ploj. pSLC ntawm Compute modules Lub eMMC nco siv ntawm Raspberry Pi Compute Module li MLC (Multi-Level Cell), qhov twg txhua lub cim xeeb ntawm tes sawv cev 2 khoom. pSLC, los yog pseudo-Ib Leeg Qib Cell, yog ib hom NAND flash nco tshuab uas tuaj yeem siv tau hauv MLC cov khoom siv sib xws, qhov twg txhua lub xov tooj sawv cev tsuas yog 1 ntsis. Nws yog tsim los muab qhov sib npaug ntawm kev ua tau zoo thiab kev ua siab ntev ntawm SLC flash thiab tus nqi-zoo thiab muaj peev xwm ntau dua ntawm MLC flash. pSLC muaj kev sau ntawv siab dua li MLC vim tias kev sau cov ntaub ntawv rau cov hlwb tsis tshua muaj kev hnav. Thaum MLC yuav muab ib ncig ntawm 3,000 txog 10,000 sau cov voj voog, pSLC tuaj yeem ua tiav cov lej ntau dua, nce mus txog qib siab ntawm SLC. Qhov kev ua siab ntev ntxiv no txhais tau tias lub neej ntev dua rau cov khoom siv siv pSLC thev naus laus zis piv rau cov uas siv tus qauv MLC.

MLC yog tus nqi ntau dua li SLC nco, tab sis thaum pSLC muaj kev ua tau zoo dua thiab kev ua siab ntev dua li MLC ntshiab, nws ua li ntawd ntawm tus nqi ntawm lub peev xwm. Ib qho khoom siv MLC tau teeb tsa rau pSLC yuav muaj ib nrab ntawm lub peev xwm (lossis tsawg dua) nws yuav muaj raws li tus qauv MLC ntaus ntawv vim txhua lub xov tooj tsuas yog khaws cia ib me ntsis xwb tsis yog ob lossis ntau dua.
